SIGNAL-LAMP-RAISING- DEVICE.

Specification of Letters Patent.

Application filed April 1, 1911.

Patented Dec. 26, 1911.

Serial No. 618,301.

To all whom it may concern:

Be it known that I, JOHN D. SAMPLnY, a citizen of the United States,residing at Buchanan, in the county of Guadalupe and Territory of NewHexiomhave invented new and useful Improvements in Signal-Lamp RaisingDevices, of which the following 1s a specification.

The invention relates to a signal lamp raising device for semaphores.

The primary object of the invention is the provision of a device of thischaracter in which a lamp may be raised, so as to position the samedirectly in rear of the signal lens in a semaphore arm, withoutrequiring the use of a ladder, or necessitating an attendant climbingthe semaphore ole. p Another object of the invention is the provision ofa device of this character in which the signal lamp or light may beraised or lowered in a ready and convenient manner, and also that willpermit the adjustment of the light or lamp when positioned in rear ofthe lens in the semaphore arm, so as to permit the proper positioning ofthe lantern or light for the reflection thereof through the said lens ofthe semaphore arm, whereby trains may be signaled.

A further object of the invention is the provision of a device of thischaracter for use on semaphore poles, whereby the signal light orlantern may be raised or lowered to and from its place by an operatorwhen standing upon the ground, thereby obviating the necessity ofclimbing the semaphore ladder or its pole.

A still further object of the invention is the provision of a device ofthis character which is simple in construction, thoroughly reliable andetficient in operation, and inexpensive in manufacture.

With these and other objects in view, the invention consists in theconstruction, combination and arrangement of parts, as will behereinafter more fully described, illustrated in the accompanyingdrawings, and pointed out in the claims hereunto appended.

In the drawings: Figure 1 is a side elevation of a semaphore, showingthe device mounted upon its pole with the signal light or lantern inlowered position. Fig. 2 is a similar view, showing the light or lanternin raised position and in rear of the lens in the semaphorearm. Fig. 3is a horizontal sectional view on the line 33 of Fig. 1. Fig. 4 is afragmentary vertical sectional view through the support and the turningbar, showing the manner in which the latter may be adjusted relative tothe support.

Similar reference characters indicate corresponding parts throughout theseveral views of the drawings.

Referring to the drawings by numerals,

5 designates a pole of the ordinary well- Fixed to and rising from theupper end of I the semaphore pole 5 is a hanger or support, comprising ametallic strip 10, the ends 11 and 12 thereof being bent at right anglesto said strip 10, the end 12 being of greater length than the end 11which is suitably secured to the pole. Connected to the end 12 and tothe strip 10 is a brace member 13 which strengthens the said end 12.Swiveledin the end 12 is a depending pin 14, the

same being engaged in an elongated slot 15 formed in the inbentextremity 16 of a turning bar 17, the same being flat throughout agreater portion of its length, and is provided at its opposite extremitywith a squared shank 18 fitting within. a correspondingly-shaped opening19, formed in a bearing ear 20 suitably fixed to the pole 5, the saidbearing ear 20 being fixed to the pole spaced from the ground.

Journaled in the turningbar 17 at the top end thereof is a guidepulley21, over which is trained an endless cable 22, the latter carrying aclip 23 to which is detachably connected a signal light or lantern 2 1,which is of the ordinary well-known construction. Thus upon actuatingthe endless cable or rope 22, the lantern 2 1 may be raised or loweredon the turning bar 17 and when in raised position near the upper end ofthe said turning bar 17, the latter may be shifted or rotated a quarterturn for bringing the said lantern 24 directly in rear of thetransparent glass disk 9 in the semaphore arm 7 whereby the rays oflight from the lantern may be carried through the said disk for thesignaling of trains.

Threaded on the pin 14 above and below the inturned extremity of theturning bar 17 are jam nuts 25, which lock the turning bar in adjustedposition. Upon loosening the nuts 25 on the pin 14, the turning bar 17may be adjusted for bringing the same closer to or farther away from thesignal pole 5, thereby centeringthe lantern 24 with respect to thecolored disk 9 in the semaphore arm 7 when the lantern 2 1 has beenraised and positioned in rear of the said disk in the semaphore arm.After the adjustment has been made, the nuts 25 are tightened againstthe inturned extremity 16 of the turning bar 17 to sustain it inadjusted position with respect to the pole. v The squared shank 18 whenengaged in the squared opening 19 in the bearing ear 20 will lock theturning bar 17 against rotation, but upon disengagement of said shank 18from the said opening in the bearing ear, the said turning bar may beshifted when the lamp has been raised, whereby it may be swung free fromthe pole to permit the lowering thereof, or when the same has beenlowered and itis desired to raise it for swinging the same into positionrearwardly of the disk in the semaphore arm.

What is claimed is:

' 1. The combination with a semaphore pole, of a support fixed to theupper end thereof and having a right angular extension, a pin swiveledin the free end of said extension, a turning bar having an inbentelongated slotted end slidably engaging saidpin, means locking theinbent end in adjusted position on the pin, means normally holding thebar againstturning movement, and lantern raising and lowering meanssupported by the turning bar. r 2. The combination with a semaphorepole, of a support mounted thereon, a pin swiveled in said support, aturning bar arranged parallel with the pole and having an elongatedslotted inbent end slidably engaging said pin, .jam nuts carried by thepin and working against the inbent end of the bar for holding it inadjusted position on the pin, a squared shank formed on the bar at. itsopposite end, a bearing ear fixed to the pole and having a squaredopening for receiving said shank for locking the turning bar againstmovement, and lantern raising and lowering means carried by the saidturning bar.

3. The combination with a V semaphore pole, of a support mountedthereon, a pin swiveled in said support, a turning bar arranged parallelwith the pole and having an elongated slotted inbent end slidably en-"gaging said pin, means on the pin engaging the inbent end of the bar forholding it in adjusted position 'on the pin, a squared shank formed onthe bar at its oppositeend,

a bearing ear fixed to the pole andHhavin-ga squared opening forreceivingsaid; shank for locking the turning bariag'ainst movement,lantern raising and lowering means carried by the said turnin'gbar,- andmeans for detachably connectingjag-lante'rn to said last-named means.

In testimony'whereof I'afliX my signature in presence of two-witnesses.
